In January, June, and July 1938, and June 1939 parts of Texas experienced floods that exceeded previously recorded stages at many places and that were unusually high over reaches of several hundred miles on the streams of the State. This report presents records of precipitation at several hundred places; 10 isohyetal maps; records of peak stages and discharges and of daily mean discharges during t

This report covers Angelina County, Texas, of which Lufkin is the county seat, and parts of Nacogdoches and other adjacent counties. The area is underlain by a series of sands, clays, and shales of Eocene age that dip, in general, southward at an angle a little greater than that of the land surface, which also slopes southward, thus creating favorable artesian conditions. The formations cropping o

Balmorhea is the center of a thriving farming community, the lands of which are irrigated with water derived chiefly from large springs but partly from the storm flow of Toyah Creek. The storm flow of the creek and a part of the winter flow of the springs is stored in a reservoir near Balmorhea and used later to supplement the flow of the springs. The present investigation was made to determine th

The first gaging station In Texas urns established on the Rio Grande at El Paso on May 10, 1889, under the provisions of the Act of Congress of October 2, 1888, which authorized the organization of the Irrigation Survey by the United States Geological Survey. A few miscellaneous measurements of streams In central Texas, between Del Rio and Austin, were made, by C. C. Babb of the Geological Survey

In localities where highly mineralized water is present in beds above and below the beds that yield the supplies of fresh water it is necessary to be able to locate leaks in wells in order to know whether the wells are being contaminated through holes in the casings or whether the fresh water supply is failing. Four general methods of detecting salt-water leaks have been used. In the pumping metho

Duval County is situated in southern Texas, 100 to 150 miles south of San Antonio and about midway between Corpus Christi, on the Gulf of Mexico, and Laredo, on the Rio Grande. The county lies on the Coastal Plain, which for the most part is low and relatively featureless. Between the Nueces River and the Rio Grande in this part of Texas the plain is interrupted by an erosion remnant, the Reynosa

Webb County is in southwestern Texas and is a part of the Winter Garden district. The purpose of the investigation here recorded was to determine the source, quantity, and quality of the ground water used for irrigation and other purposes in the area.

This report is based on an investigation by the United States Geological Survey, the Texas State Board of Water Engineers, and the Texas State Board of Health to determine the ground-water resources of Uvalde and Medina Counties, especially in relation to irrigation, both in these counties and in the counties to the south where water is obtained for irrigation from the Carrizo sand and younger for

The water discharged from the large springs of San Antonio and most of the deep wells of the San Antonio area comes from a common reservoir in fissures and solution channels in the Edwards limestone. The water enters the limestone in a zone of outcrop along the Balcones escarpment, which crosses the northern parts of Bexar and Medina Counties and extends a long distance both to the east and west o

Abundant supplies of fresh water are obtained from deep artesian wells In all parts of Kleberg County. The water is derived from a stratum of sand, 10 to 150 feet thick, which usually has been referred to the Goliad sand but possibly may be at the base of the LIssie formation. The top of the sand Is reached at depths of around 400 feet In the western part of the county, 600 to 700 feet In the loca

Atascosa and Frio Counties are in southwestern Texas and form a part of the Winter Garden district. The purpose of the investigation here recorded was to determine the source, quantity, and quality of the ground water used for irrigation and other purposes in the area.
